To a'ZZ 'whom it 'may concern:

Be it known that I, EDwIN F. HULBERT, citizen of the United States, residing at South Norwalk, in the county of Fairfield and State of Connecticut, have invented Certain new and useful lmprovementsin Refrigerators, of which the following is a specification.

This invention comprehends certain new and useful improyements in refrigerators and has for its primary object an im-proved Construction and arrangement of parts whereby the circulation of air through the Cooling' Chamber' and to and from the storage or food Chamber, will be effectively promoted and whereby a maximum circulation of the air currents in and around the Cooling Chamber, in proportion to the size or area of the same, will be efected. And the invention also has for its object an improved Construction of tray, upon which the ice is in-.

tended to rest, said tray forming part of the air Circulating means and being preferably detachable and capable of being readily inserted in place, said tray embodying a series of pipes which extend entirely across the bottom of the casing in which the ice is placed, and, together with openings hereinafter specified, establishing Communication between the interior of said Casing and the interior of the food Chamber.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective View of a refrigerator embodying the improvements of my invention; Fig. 2 is a Vertical longitudinal sectional view thereof, parts being shown in front elevation; Fig. 3 is a transverse sectional View, the section being taken substantially on the line 3-3 of Fig. 2; and, Fig. 4 is a detail perspective view of the tray upon which the ice is intended to be placed.

'Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the body portion of my improved refrigerator, said body portion being of any desired Construction and design and formed with non-conducting walls of any desired The refrigerator embodies a lower storage or food Chamber A and a distmCt Cooling Chamber vB thereabove. Preferably, ea-Ch Chamber is provided with its own door, as ln'dlcated in Fig. 1. The upper or Coollng Chamber .B 1S divided into two Compartments B' and B2, this being effected in the present instance by means of a prefera bly metal Casing C which embodies Vertical side walls 2 which extend parallel to the walls of the outer compartment B', from front toright, as shown, and an upper Connectlng horizontally disposed wall 8, the sides 2 and top 3 being spaced from the main walls of the Cooling Chamber, whereby to provlde a clear passage all around the Caslng C. The said Casing is provided in its top 3, and preferably at the junction of the top of the sides 2, with any desired number of apertures 4 that establish communication between the exterior and interior of the Casmg. The space surrounding the Casing O Communicates with the interior of the food Chamber A by means of any desired number of apertures 5 which in the present instance are arranged in two series extending from front to rear on opposite sides of the casing C and at the bottom thereof. In other words, the apertures 5 are formed in the top of the food Chamber and in that portion of said top which is outside of the Casing O.

D designates the tray upon which the ice is supported within the Casing C. In the present embodiment of the invention the tray D Comprises a bottom 6, sides 7 extending from front to rear, a front 8 and a back 9, the two sides, front and back, extending vertically, as shown, and the back being formed at its upper edge with a rearwardly extending flange 10 adapted to abut with its rear edge against the rear wall of the Cooling Chamber and thereby produce underneath the fiange and distinct from the cooling Chamber, a laterally extending air Chamber 11 which Communicates with the lfood Chamber A by means of a series of openings 12 formed in the top of the food Chamber and extending in a series Close to and parallel with the rear wall thereof. In addition to the body portion of the tray just described, said tray includes a series of tubes 13 which extend side by side at any desired distance apart, preferably close together, and on which the ice is adapted to directly rest. These tubes 13 are supported at their front ends in recesses 14 which are formed in the front 8 of the body portion of the
